Glenn raced his motorcycle 30 times last season. He finished first 12 times, second 5 times, and crashed in 9 races. What percent of the races did he finish second?
16.6% of the races!
Divide the amount of times he placed second by the amount of races he participated in. That means you have to do 5/30. Then multiply it by 100! That is how you get 16.6%. The same goes for the other situations, if you were trying to find the percentage of how much he placed first, all you'd have to do is divide 12/30 and multiply by 100.
